To all it my concern:

I, CnAUs O. BRANDELL,

of Illinois, have invented certain new and useful Improvements in Tile-Making Ma-' chines, of which the' following is a specification. I

This invention relates to tile-making machines, and has for its object to provide a machine for making tile-of concrete or the like, whereby the tile may be mechanically formed and colored without the necessity of manual treatment.

The object of my invention consists in the provision of mechanism of the type described above, wherein the constituent matesv rial will be, automatically deposited upon pallet or mold boards in such manner as to enable it to be readily treated in subsequent operations, this delivery being made as the boards pass beneath the main supply.

Another object consists in the provision of means for tamping and preliminarily smoothing the upper portion of thejmaterial as'the same is conveyed through the machine, this machine simulating the manual operations of present day tile-making, as will'be more fully hereinafter described.

A further object consists in'the provision of means-for depositing coloring and finishing material on the upper suface .of thepartially formed tile during its progress.

Another object consists in the provision of automatic means for dividing adjacent tile as they travel .tl'lltfilgh the machine.

Another object consists-in the provision of means for automatically and efficiently controlling and finishing the app r surface of the tile, during which operation e same is maintained in fixed position.

. Another object consists in the provision of means to position each tile and board during the trowelling operation, such means being operative to true up the ends of the tile.

Another object consists in the provision of means for removing and conveying each allet board after the trowelling operation mm the main portion of the machine transversely thereto.

' Another object consists in the provision of means for coloring and finishing one end of each tile.

Still another object consists in the provision of inter-related driving and actuating means,or the means set forth above, whereby each of said means will 'fimction in proper. co-relation and at the proper spec and time.

Other' objects consist in the provision of means for carrying out the steps incident to the production of the completed tile.

.These and other objects of the invention will be described in the following cation and shown in ings, in which 'Figure I isa plan view of an embodiment of my machine, a portion of the hopper being broken away for .clearness;

Like numerals refer to. like elements throughout the drawings, in Which 1 designates the form of pallet or molding board shown in Fig. II, it being understood that the design and form of this board may be varied to accord with the character of tile which it is desired to produce. This board is rovided with the upper surface 2, the raised central rib 3, the tongue 4 at one side thereof to form the grooves 5, and recesses 6 on either side of the rib are rovided at the ends of the board. In Fig. VII I have shown a tile 8 partially formed by the board described, the coaction of the mechanism with the board resulting in the completely formed tile having the central raised rib 9 and the raised rib 10 at one side, beneath which are provided the tongues 11, forming grooves 12 on the. lower face of the tile, while at the other side are rovided the tongues 13 spaced apart to orin the groove 14, this construction permitting interlocking engagement of the tongues and grooves 11-12 of one tile with the tongues and groove 13-44 on the upper face of the adjacent tile when assembled in building operations or the like. At the ends of the tile 8 are provided the depending lugs 15, spaced a art to define a central recess 16, within w ich is intended to fit the central rib 9 of subjacent tile, similar recesses being provided at the sidesof adjacent tile by the lugs 15 of such tiles, as willbe readily understood. This tiletis of conventional construction, and needs no further explanation herein.

The machine comprises amain hopper 18, tapering toward its bottom or oint of dis charge, as shown in Fig. IV, or example. This ho per is located above the body of the mac me, being supported upon suitable see Fig. III.

a part of and su ported by the frame 20-.-

he hopper 18 is provided with the rectangular portion 18 at its bottom, which is open. A surrounding collar 21 serves to strengthen and support the rectangular. ortion 18 of the hopper 18.

Locate at the bottom of the hop er, and normally affording a closure there or is a plurality of louvers 23,-see Figs. VIII and XI, for example. There is also provided one stationary louver 24, for a purpose described below, Each of the louvers 23 is" carried upon and between a pair of brackets 25, having table portions 25" for that purpose. Each of the brackets is further vided with a depending lu or arm 26, t ese arms being pivotally held etween straps 27 rivets or pins 28 serving to hold them in pivoted relation. At their outer portion the brackets are provided with circular bosses 28, carrying the trunnions 29, which are journalled in the reciprocating plates 80. Rollers 31 are supported on suitable bolt ins 32 projecting inwardly from the upri it supports 19-see Fig. XIII, for examp e. These rollers are flanged at 31, intermediate their extremities, to guide the .plates 30 against lateral movement. The straps 27, brackets 25, and plates 30 form a reciprocating frame su ported by the roller's 31. The rearmost lar to the brackets 25, save that it is provided' with an additional upwardly and outwardly extending arm 25", which terminates in angularly disposed extremity 25 -see Fig. VIIInormally lying above the plate the extremity 25, for a purpose to be herestandards 19 projectingupwardly from and I carried upon the table 20, in turn forming racket 25 is simi- 30. An adjusting screw 35 is threaded into portions 24 which are directly secured, by

rivets or the like, to the plates 30.

Extending betweeen the sides of the machine, beneath the top thereof, is the rock shaft 37, to which is secured theupwardly extending lever 38 and the angularly disposed-downwardly extending lever 39. At its upper end the'lever 38 is pivoted at 38 to a link 40, which, in turn, is pivoted at its other end 40 between the ends of straps 27see Figs. IV and XII. A rotatable or driven shaft 43 extends between the sides of the machine, and secured thereto is the cam wheel 44, having a cam groove 44, in which rides a roller 45 carried by the lever 39. This construction is such that rotation of the shaft. 43 results in the reci rocation of the lever 38 to and fro. hen

in normal or closing position the lever plates, ment to Assuminga mass of concrete of the proper consistency to have been placed in the hopper 18, the tilting of the louvers 23 will permit a partial movement of such concrete, and lateral shifting of the louvers in their tilted position will serve to cut strips or ribbons of the concrete from the main body, which will be deposited upon subjacent pallet boards,as shown in Fig. IV for example. The cam wheel 44 is so constructed and driven as to time this cutting and depositin of the concrete in proper co-relation wit the coacting mechanlsm.

At the left of the machine is rovided the inclined way 50, composed o a pair of inclined sides, upon whichare journalled the rollers 51, constructed to support and permit passage of the empty pallet boards 1.

Carried by the rotating shaft 43 is a pair of s rocket wheels 55, shown, for example, in ig.. III. A pair of chains 56extend around and engage the sprockets and also serve to transmit rotation thereto. At intervals corresponding to the length of the pallet boards 1 are provided the blank strips 57 and the feed strips 58, these strips being 'ate face portion arranged in pairs and alternately, as illustrated in Fig. III the members of each pair-being slightly spaced a art. The feeding strips differ from the b ank strips only engaging projections 58 arranged to engage the depressed e'nds 6 of the pallet boar s, as indicated in Fig. IV. Assuming the upper run of chain 56 to be moving from left to right as viewed in FigQIV and a supply of empty boards 1 to be on the runway 50, the first of such boards Will be engaged by a. pair of feeding, strips 58 and drawn upon the chain 56 mitil the depressed portions of the board at its other'end are supported by the blank strip tollowing, these strips serving.

At the right of the hopper, as viewed in.

Fig. IV, for example, is provided a tamp-ingor packing member 60, comprising the arm- 61 secured to the blocks 62, which, in turn, rock shaft 63. journalled at the sides of the machine. The face 61 is proferly grooved to conform to the upper sur ace of the tile to be formed, as will be obvious, and the arc of the forward portion 61 is of flatter construction. An arm 64 projects operating rod 65 is pivotally attached to the arm 64 at one end, and at its other end is eccentricallyv and pivotally attached are carried upon the position shown in Fig. XII.

from the shaft 63. An I during these oscillations the heaped up concrete or other material is quickly and efficiently tampedor patted to perform this operation, closely simulating the hand operation of talnpin and forming a vital port1on. of my mac me. The character of the patting or tamping results in increasing the per solidification and formation. As the tile passes beneath the tamper the central portion, i. e. the portion of greater curvature, being a proper ensures its pro-.

distance above the mold board and partially rotating about its center, serves to rub and partially finish the upper surface of the tile as Well as properlydimension it asv to thickness. To sever each tile from the succeeding tiles, I provide the following mechanism: A

rotatable shaft 71 is provided, upon which is rotatably mounted a toothed ratchet wheel 72 having a plurality of shallow teeth 73,

with tapered teeth 74 located at predetermined intervals. A pawl 75 is secured to the shaft 71, having its-engaging tip so located as to lie just beneath the depressions of the sl'iallow teeth 73, butabove the deep depressions 74. A detent 78, mounted upon a suitable rod or shaft 79, normally engages the teeth of theratchet 72, t prevent reverse rotation thereof. Also carried upon the shaft 79 is the oscillating arm 80, carrying a horizontal pawl 81 in engagement with the teeth of the ratchet 72-see Fig. IX. This arm is provided with an adjustable set screw 80 which at regular intervals is struck by a reciprocating lever 82, functioning to operate another portion of the mechanism described later. spring 83, carried by the pawl 7 8, contacts with the flange 80 on thearm 80, and serves to return said arm normall after each movement of the lever 82. en the latter strikes the set screw 80 it will move the arm.

when it drops into one of the deeper depressions .74 it will engage the pawl 75 and will rock the shaft 71 during its movement. Secured to the shaft 71 is the arm 85, carrying at its outer extremity thepivoted knife,

knife 86 must be provided, and this is done .by the provision of springs 87, it being understood that the cutting movement of the knife is comparatively rapid. I

After the proper tamping and formation f the tile, the same passes beneath the hopper 90, which is provided with a dischargespout 91, a screen 92 being located at the top In the hopper is maintained a supply of coloring pigment and cement, these ingredients sifting through the screen upon the moist upper surface ofthe tile to impart a desired color and smooth exterior thereto. Located in the hopper 90 is the stirring or agitating arm 95, carried by the shaft 96, which is journalled in suit able standards 97 at the side of the hopper. Oscillation is. imparted to the stirring arm 95 by means of the rod 98, attached to the arm 99 on the shaft 96see Fig. III- -and also attached to an arm 100- carried upon the shaft 63, the

I oscillation of the latter being thereby constantly transmitted to the stirring member 0 95 to clear the screen or s'ifter 92. After 5 111, which coacts with the roller 109 to tilt,

the passage of each tile and mold board heneath the hopper 90,11 subject the former to a trowelling or finishing operation, which is performed by the following mechanism: A pair of rods 105 are locatedone on each side of, the machine, being each secured at one end to side frame members 106, which in turn, are pivoted at their opposite ends 106 to supports 107 extendin upwardly from the-top of themachine. rojecting downward from and secured to the side frame members 106 is the leg 108, which is provided with a roller 109 at its lower end. Carried by the rotatable shaft 110 is the cam at predetermined intervals, the said frame members and rods 105 about the pivotal points 106. Upon each of the rods 105 is mounted the carriage 112, comprising two pairs of groovedrollers 113 engaging the rods and slidable thereon, these rollers bein held between the plates 114see Figs. I

and XIV. The trowel member proper is "indicated by numeral 120, and is properly shaped on its under surface to conform to across the machine.

table disk 133,

trowel member is located between the'carriage members 112, as shown in Fig. XVI;

for example, being carried by the arms 122,

the trowel. .These arms 122 are providedwith the hub portions 122, which fit on and are secured to the cross rod 126 extending I The upper carriage plates 114 are provided with bearings 124 in which is journalled the rod 126, the latter extending through said hearing At the ends of the rod 126 are attached the hub portions 125 (see Fig. XVI) of arms 125, which are thus secured to the rod. These arms are pivotally engaged at their other, ends by operating rods 128. 1

It will be obvious that longitudinal move ment of the rods f 128 will tend to rotate the arms 122 and trowel 120. This rotation is limited to a slight movement by means of the lugs 112* of the lower carriage the longitudinal depressions of the tile.;' The plate'114 of the carriages 112, the purpose being that when the trowel is moving in its trowelling stroke it will be brought to bear upon the cbncrete, whereas on its return stroke it will be slightly lifted therefrom. The rod 128 is pivotally attached to the lever 82see-Fig. III-which latter .is pivoted at its other extremity at 82 adjacent the base 'of the machine, to and rotatablewith the rock shaft 130. Intermediate its extremities the lever 82 is grooved at 82", and in this groove rides the roller 131 eccentrically carried by the'rota- 134 and sprocket 135.

It will be obvious that the levers 82 oscillate back and forth, regardlessof-the position of the rods 105, the tilting of which latter is timed to permit movement of the pallet boards to trowelling position. The chain 134 is driven by the pinion 137 and drive shaft 138, to which rotation is imparted by the pulley 139, or the like. This shaft also carries the sprocket 140, engaging the chain 68. Rotation is transmitted from the sprocket 133 through shaft 142 and pin ion 143 to gear 144, mounted on the shaft 145, on which is also mounted the pinion 146 which transmits rotation to the gear 147.

carried by the shaft 110.

I provide for positive movement of the mold boards from the chain 56'to trowelling position in the following manner: lever 150 is pivoted at itslower extremity at 150. An operating rod 151 is pivotally attached to lever 150 intermediate the extremities of the latter. At its other end this operating rod is pivoted to the arm 153, carried by the shaft 130-see Fig. IIIso that the lever 150 will operate in synchronism with lever 82. The actuating wheel 133 rotates at a speed suflicient relative to the being secured which is rotated by the chain A rocking.

other mechanism to accom lish two or more trowelling strokes on eaci tile, the movement of the lever 150 being functionless du ing, such trowellingstrokes. It will be ob vious that the gpeed ofthe driving wheel 133 maybe varie to accomplish any desired number of trowelling operations for each tile. At its upper extremity the lever 150 is bifurcated at 150"see Fig. XVI-eachof the ends of the bifurcated portion being split, and between each pair of extremities thus formed isv pivoted the engaging arm 155,.earrying the rollers '154f'normally rid in against the lower side 0 the flanges of ta le 20. The rollers 154 are carried on a rod 160, which extends through the pivoted pawls 155, as shown in Fig. XVI, for example. A spring 161 extends between each end 150" of the lever 150 and the angularly bent portion 155 of the pivoted arm, this 1 spring normally functioning to hold the arm imposition to engage a pawl lug.

To position trowelling operation, and to shape the ends thereof, I provide the following mechanism shown on an enlarged scale in Figs. XVI, XVII, and XVIII. L A pair of spaced upright plates 164 and 165 are provided, the former being fixedly held against the cross strap166, through which extends and is secured a pair of rods 167. These rods are slidably mounted in ,the brackets 168 and collar 170. carried on the rods 167. Arms 171 ai'e pivoted on the bolts 172, which, in turn, are secured in'bosses 17 3 carried by the rods 167. The outer ends of the arms 171 are secured to the plate 165 by bolts 165 or the like. The arms 171 are provided with flanges 173, which are inclined at 173, thus forming a track or runway terminating in the oifset portion 17 3". Rollers'175 are se v cured by bolts 176 to lugs 17 7 carried by the frame of the machine.

Prior. to the movement of the pallet board by the lever 150 the positioning and end shaping mechanism is in the position shown in Fig. XVIII. As the pallet board'indicated in dotted lines in said figure-is moved to the right, it strikes the plate 164,

sha ing the soft concrete or other material to orm a smooth surface. The rods 167 are moved to the right with plate 164, compressing the spring 169. At the same time the arms 171 ride upwardly upon the rollers 175 to the position shown in-Fig. XVII, wherein the plate 165 contacts and smooths the end of the tile and maintains it in position during the trowelling operation. 7

During its movement from the conveyor to trowelling position the pallet rides at its sides upon the horizontal flanges 20 and by properly dimensioning and constructing the springs 169 the frictional resistance of the tile and board will ordinarily serve to maintain the plates- 164 and .165 in the position the tile properly during theshown in Fi XVII during the trowelling operation. 0 ensure againstpossible disacement by the compressed slpringg 169, ig. VI a owever, I have illustrated in latching means comprising a latch 190, having an upturned engagin end 190, over which will ride a depresse portion 6 of the board 1 in its movement to trowelling position. The latch 190 is'provided with a hub 190 rotatably mounted on the cross rod 191 between fixed collars 192 and 193. counterweight 194 extends rearwardly of the hub, and serves to maintainthe latch normally in engagin position. A transverse arm 192? extends angularly from thecollar 192- and overlies the latch arm 190, serving to limit the upward movement thereof and prevent its interference with the let board hereinafter described. The p ate 164 is provided with a slot 164, to permit extension therethrough of the latch arm.

After the completion of the trowelling operation, means'are provided for transversely removing the pallet and tile in the following manner,-see Fig. V. Uprights 200..

support the transverse frame members, constituting a transverse table 201, and between such members are located the rotating pulleys 202 rotating with and carrying the belts 203, the upper runs of which .are located above the plane of the table201. A air of transverse spaced bars 205 are 'provi ed extending partially across the main table 20, the side members of the latter and the flanges 20 being recessed or cut away, as indicated at 206, to permit the extension therethrough of the bars 205-see' Figs. I and XXII. These bars are normally below the plane of the pallet boards, and are supported upon I pedestals 208, in turn carried upon subja: cent rods 209--see Fig. V. Each of these rods extends through and is supported by the lugs 210 of the transverse triangular brackets 211. The pedestals 208 are slidable'upon the rods 209, and one of each set thereof is provided with a depending lug 208see Fig. XXII. A link 212 is pivoted at one extremity to the lug 208 and at its other extremity between the ends of the bifurcated lever 214, which, in turn,'at. its extremity is secured to the rod 215. Likewise secured to the'rod 215 is a crank 216, to the other end of which is pivotally attached the ,link 217, in turn pivotally attached through the link mechanism to the lever 219,-see Fig. XXIV, for example. This lever is carried by and rotatable with the rod 220, which is journalled in the side frame of the main portion of the machine. The lever 219 is provided with a rearwardly extending arm 219 which carries a roller 219 riding in the cam oove 220of the cam 221, which is'carrie u on and rotated by the shaft 110. It will obvious that actuation ofthe lever 219 by the cam 221 Will result in a sliding of thebars 205 laterally and transversely of the main table of the machine. The rod 215 is suitably journalled in triangular brackets 213' extending outwardly from the main frame of the machine, see Fig. XXII for example.

The brackets 211 are carried by the vertical rods 230, which are journalled in bearings 231 and 232 for vertical movement. A cross bar 234 extends between and connects the rods 230. A link is pivotally attached tothe-cross bar 234 at one. extremity,

and at its other extremity is pivotally attached to the lever 236, pivotally mounted upon a rod at 237 carried by the main frame of the machine, see Figs. XXII and XXIII.

At one end the lever carries a roller 236,

which is attached at the under side of a cam disk 240 carried upon the shaft 110 and so constructed as to reciprocate the rods 230 vertically, and thereby the brackets 211. This vertical movement is transmitted to the bars 205, and the resultant of the two motions by proper construction of the cam and disk is a substantially rectangular or the link 212.

elliptical one, by which the bars are moved transversely beneath the pallet board on the flanges 20, thereafter engaging the pallet and tile and moving the same transversely Prior.

of the main frame of the machine. to the movement of the bars 205 to the left, as viewel 'in Fig. XXII, they are first lifted, as will be obvious, and the lever 214 will exert a substantially axial thrust on Thereafter the bars move downwardly, depositing the pallet upon the shelf strips 245 carried by the main frame of the machinesee Figs. VI and XXII.

In the next cycle the bars will engage the pallet previously deposited upon the shelf strips and advance the'same further, de-

positing it upon the belts 203, after which it is conveyed to any suitable place for collection.

During the support of each pallet and tile upon the'shelf strips 245, means are actuated to color one end of the tile, i. e. that end whichis exposed in use. This is accomplished by the mechanism shown, for example inFig. VI, consisting of a liquid pigment tank 260 -see also Figs. I and IVthis tank being supported on the trans Verse frame of the machine.

outwardly from the pedal,

A rotatable shaft 261 extends across the tank 260 and carries a-pair of arms 262,v

shown in ig. VI. At'the outerend of the shaft 261 is provided a pinion 269 in mesh with a gear 270 carried upon the shaft 271,

which also carries a sprocket 272 actuated by the chain 273, driven from the sprocket 274 and shaft l10see Figs. I and III. In this manner'rotation is transmitted to the shaft 261 in the direction of the arrows, as shown in Fig. VI. The blades or pedals are so located that after dipping into the fluid pigment in the tank 260 they will wipe or rub the adjacent end of the tile, the springs 266 permitting of slight yielding during this movement, whereby one end of the tile is not only colored but is smoothed, this being the end exposed in use.

Itis believed that the description of the various parts and elements has been sufliciently outlined to enable those skilled in the artto understand the operation of the mechanism; and it is therefore not believed. to be necessary to describe the. operation of the machine in'detail here. 2
